Add new cards directly on MyBoard

As an end user, I would like the option to add new cards directly on MyBoard. Use case is such that not every card will have its home on another board which feeds into the MyBoard. Such things could be tasks that fall out of bigger projects or simply things that I have to do that are not pertinent to others in the organization.

My current workaround: I created a new personal collection of boards, added a new list and put all personal tasks in that list and send them to MyBoard from there.
